I bought a 1991 Nissan Sentra about two weeks ago. It had set for over a year. We got it running like a top, and now all of a sudden its starting but it is backfiring, and has no power at all. Please help me. My brother in law changed the wires for me, I was hoping one might be crossed, I know that the order is 1342 but I need a pic and cannot find one. Any ideas?
